中微子在粒子对撞机上大量产生，但从未在对撞机上检测到中微子。对撞机能以极高的能量产生各种口味的中微子和反中微子，因此它们与其他来源的中微子有很强的互补性。FASER，LHC的前向搜索实验，是提供对撞机中微子的第一次探测和研究的理想场所。我们调查中微子研究的前景与FASER，FASER的一个建议的组成部分，由乳胶膜交错与钨板的总目标质量为1.2吨，被放置在轴上的FASER的前面。我们估计了中微子通量和相互作用率，描述了FASER探测器，并分析了信号和原始背景的特性。对于在2021- 2023年14 TeV LHC的运行3期间收集的积分光度，大约1300个电子中微子，20，000个μ子中微子和20个τ中微子将在FASER中相互作用，平均能量为600 GeV至1 TeV。有了这样的速率和能量，FASER将测量中微子在当前不受约束的能量下的横截面，将约束正向粒子产生的模型，并可能打开一个超越标准模型的物理学新窗口。
Neutrinos are copiously produced at particle colliders, but no collider neutrino has ever been detected. Colliders produce both neutrinos and anti-neutrinos of all flavors at very high energies, and they are therefore highly complementary to those from other sources. FASER, the Forward Search Experiment at the LHC, is ideally located to provide the first detection and study of collider neutrinos. We investigate the prospects for neutrino studies with FASER, a proposed component of FASER, consisting of emulsion films interleaved with tungsten plates with a total target mass of 1.2 t, to be placed on-axis at the front of FASER. We estimate the neutrino fluxes and interaction rates, describe the FASERdetector, and analyze the characteristics of the signals and primary backgrounds. For an integrated luminosity ofto be collected during Run 3 of the 14 TeV LHC in 2021–23, approximately 1300 electron neutrinos, 20,000 muon neutrinos, and 20 tau neutrinos will interact in FASER, with mean energies of 600 GeV to 1 TeV. With such rates and energies, FASER will measure neutrino cross sections at energies where they are currently unconstrained, will bound models of forward particle production, and could open a new window on physics beyond the standard model.
